<embodiment 1>

Hereinafter, being illustrated referring to an embodiment of the attached drawing to condensate discharging device of the invention.Here, Fig. 1 It is the schematic diagram for indicating the structure of condensate discharging device of present embodiment, Fig. 2 is the schematic diagram for indicating the structure of choke block, Fig. 3 is the schematic diagram for indicating the stable state of condensate discharging device, and Fig. 4 is the starting state for indicating condensate discharging device Schematic diagram.

The condensate discharging device of present embodiment, heat exchanger, drying machine refrigerating and heating combined equipment etc. using steam as In the various steam heating equipments that heat source utilizes, in order to which the leakage of steam is suppressed to minimum limit, and should from equipment removal Condensate liquid and be utilized, be installed on the back segment (downstream side) of steam heating equipment (not shown), the condensate liquid being formed in the interior thereof The midway of access is provided with throttle.Moreover, draining is that condensate liquid passes through throttle because of pressure difference and is discharged to outside equipment.

Specifically, as Fig. 1 is showed schematically, the condensate discharging device 1 of present embodiment, not make newly to steam The mode that gas leakage the condensate liquid DR for importeding into input side is discharged to outside device, by multiple throttling unit 10U_1~NHollow It is configured in series in cylindric shell HG.In addition, in the present embodiment, being formed with threaded portion in the peripheral part of shell HG SC is installed so as to be screwed into the piping etc. set.

Each throttling unit 10U_1~NIt is configured to include: the throttle orifice 11h with same diameter_1~NPlate (be round in this example Plate) choke block 12P_1~NAnd have and choke block 12P_1~NIdentical outer diameter and in choke block 12P_1~NBack segment formed Pressure reduction space (pressure-reducing chamber) 14S_1~NHollow disk-shaped pressure reductor 14P_1~N.And in the present embodiment, above-mentioned throttling list First 10U_1~NIt is configured with several sections (multistage) in series along the condensate liquid drain passageway formed in shell HG.

As Fig. 2 is showed schematically, choke block 12P is formed by following two, it may be assumed that throttle orifice is (in hereinafter also referred to Heart throttle orifice 11hc) formation that is open in its center center choke block 12Pc (referring to Fig. 2 (a)) and throttle orifice is (hereinafter also referred to Eccentric throttle orifice 11hd) (join in the eccentric choke block 12Pd that its peripheral portion (therefrom on the circumference of heart septum distance d) opening is formed According to Fig. 2 (b)).In addition, it is the same diameter of 1~2.5mm (in present embodiment that throttling opening diameter, which is formed as its diameter phi, In be φ 1.5mm).

In addition, each pressure reductor 14P_1~NWith with above-mentioned choke block 12P_1~NIdentical outer diameter, by cricoid gasket seal (annular shim) is formed, and is formed with subtracting for same volume with identical opening diameter (in this case, it is φ 14.00mm) setting Press space (pressure-reducing chamber) 14S_1~N。

In addition, in the present embodiment, choke block 12P_1~NWith pressure reductor 14P_1~NIt is the thin plate of stainless steel, and shape As identical thickness (in this case, it is 1mm).Throttling is formed with the seperated plate-shaped member of same material, identical thin and thick in this way Plate 12P_1~NWith pressure reductor 14P_1~NEven if thus also making choke block in the case where being applied with unexpected load along axial direction 12P_1~NWith pressure reductor 14P_1~NIt is integrally displaced (deformation) to same direction, and pressure reduction space and throttle orifice is integrally formed Previous structure is compared, and the in addition setting seal members such as gasket are not had to, for the row of the draining when the starting until when stablizing The variation of outflow can maintain leakproofness steadily in the long term.

In addition, above-mentioned choke block 12P_1~NAnd pressure reductor 14P_1~NThickness be preferably 1~2mm.If 1mm hereinafter, then Intensity is insufficient, if 2mm or more, then for draining the tracing ability (adaptability) of the variation of delivery flow, with axial length The pipe distribution operation of increase reduces.

In addition, in the present embodiment, the throttling unit 10U of most back segment_NVia the collar 15 of hollow cylindrical by bullet The edge spring gasket SW axially presses bearing.

Moreover, in the present embodiment, adjacent each throttling unit 10U_1~NThrottle orifice 11h_1~N, in condensation liquid stream Road direction (hereinafter referred to as axial) front and back, the mode being configured on same straight line radially displaceable (bias) configure shape respectively At.

Specifically, in the throttling unit 10U of most leading portion (most upstream side)₁Configured with center choke block 12Pc.In addition, Eccentric choke block 12Pd can be configured, but in this case preferably so that bias throttle orifice 11hd is located at the side than center on the lower The phase of formula adjustment configuration.It, can be by steam thereby, it is possible to utilize imported draining DR more reliably to seal throttle orifice 11h Leakage prevents trouble before it happens.

In addition, in the throttling unit 10U of most downstream side (discharge side)_NConfigured with center choke block 12Pc.Thereby, it is possible to press down System is from central part discharge draining DR and to the etch of the piping in downstream side etc. (corrosion function).

On the other hand, in intermediate throttling unit 10U_2~(N-1)Configured with eccentric choke block 12Pd, and adjacent bias Choke block 12Pd adjusts configuration in such a way that the position of eccentric throttle orifice 11hd differs 180 °, and thus, it is possible to true to the maximum extent It protects flow path length (flow path length that appearance can be increased).In addition, the phase of the eccentric orfice 11hd of adjacent eccentric choke block 12Pd Potential difference, more preferably at least ± 90 ° or more.

In this way, making axially adjacent each throttle orifice 11h_1~NIt configures to be formed with mutually deviating (bias) radially, by This is capable of forming complicated flow path, is capable of increasing the pressure loss for the fluid to be leaked out, and reduces leakage rate, promotes to improve leakproofness So-called labyrinth effect.Furthermore it is possible to increase the flow path length of appearance, therefore the throttling unit of multistage can be shortened 10U_1~NAxial length, can be improved the connection operation to connections such as pipings.

In addition, by by pressure reductor 14P_1~NThickness defined range be set to it is relatively thin (shorten pressure-reducing chamber 14S_1~N's Depth), the production of the turbulent flow (vortex, spiral flow) in pressure reduction space caused by single layer fluid SF when thus, it is possible to prevent as starting It is raw, can promote to drain DR and be rapidly discharged, and the length of depth direction can be reduced, help to improve pipe distribution operation, Device miniaturization.
